Live coverage: SpaceX’s next Falcon 9 moved to launch pad for hotfire test

After several near-misses in tries to catch payload shrouds jettisoned from Falcon 9 rockets climbing into space, a high-speed boat tasked with retrieving the fairings for SpaceX to reuse has been upgraded and dispatched into the Pacific Ocean ahead of a launch Wednesday from Vandenberg Air Force in California.

The scheduled launch Saturday of two commercial BlackSky Earth-imaging satellites from New Zealand will double as an opportunity for Rocket Lab to test an enhanced heat shield on its Electron booster, an upgrade that should allow the company to recover rockets in better condition for eventual reuse.

With U.S. military demand waning in coming years, United Launch Alliance has multiple openings in its Atlas 5 launch manifest in 2017 and 2018 available to commercial customers with as little as three months’ notice, according to company officials.
